Vertex-degree based eccentric topological descriptors of zero divisor graphs of finite commutative rings

Abstract

A graph \( G(R) \) is said to be a zero divisor graph of a commutative ring \( R \) with identity if \( x_1, x_2 \in V(G(R)) \) and \( (x_1, x_2) \in E(G(R)) \) if and only if \( x_1 \cdot x_2 = 0 \). The vertex-degree-based eccentric topological indices of zero divisor graphs of commutative rings \( \mathbb{Z}_{p^2} \times \mathbb{Z}_{q^2} \) are studied in this paper, with \( p \) and \( q \) being primes.
